Error Reporting
Some of the existing E_ERROR conditions have been
converted to something that can be caught with a user-defined error
handler. If an E_RECOVERABLE_ERROR
is not handled, it will behave in the same way as
E_ERROR behaves in all versions of PHP. Errors of
this type are logged as Catchable fatal error.
This change means that the value of the E_ALL
error_reporting constant is
now 6143, where the previous value was 2047. Because PHP constants have
no meaning outside of PHP, in some cases the integer value is used
instead so these will need to be adjusted. So for example by
setting the error_reporting mode from either the
httpd.conf or the
.htaccess files, the value has to be changed
accordingly. The same applies when the numeric values are used
rather than the constants in PHP scripts.
As a side-effect of a change made to prevent duplicate error messages when
track_errors is
On, it is now necessary to return FALSE from
user defined error handlers in order to populate
$php_errormsg. This
provides a fine-grain control over the levels of messages stored.
